A Check-List of the Coccidae

Abstract

Anyone who will take the trouble to peruse the " Zoological Record" will see that the present is a time of unusual activity among coccidologists. In the last volume to hand, that for 1893, nearly four pages are occupied by the abstract of the literature on this family, as against three pages for the rest of the Homoptera! Before many years have passed, the Catalogue general des Hemiptbres of M. Severin will have reached the Coccidae, and we may then expect to be presented with an elaborate bibliographical index to the group. In the meanwhile the works of Signoret, Comstock, Maskell, and the forthcoming list of American Homoptera by Ashmead, will greatly assist us in reviewing the subject; but I have thought that a check-list, complete to date, would be a noteworthy convenience at the present time.
